PHILADELPHIA, PA--(HealthWire)--December 13, 1996--HEMISPHERx BIOPHARMA INC. (NASDAQ: HEMX, HEMXW) and Temple University announced today that they settled their legal disputes regarding the license agreement between the parties covering the Oragen(TM) drugs. The parties have signed the documents required to consummate their settlement. In August 1988, the Company entered into a pharmaceutical use license agreement with Temple University. Under the terms of this agreement, Temple granted the Company an exclusive world-wide license for the commercial sale of Oragen(TM) products using patents and related technology held by Temple until the last to expire of any related patents then or thereinafter issued. In July 1994, Temple terminated the agreement. In November 1994, the Company filed suit against Temple in the Superior Court of the State of Delaware seeking a declaratory judgment that the agreement was unlawfully terminated by Temple and therefore remained in full force and effect. Temple filed a separate suit against the Company seeking a declaratory judgment that its agreement with the Company was properly terminated. These legal actions have all now been terminated. Under the settlement, the parties have entered into a new pharmaceutical use license agreement that is equivalent in duration and scope. "We are pleased to have resolved this issue and reestablished a close, cooperative relationship with Temple," said Dr. William A. Carter, Chief Executive Officer of HEMISPHERx. "We look forward to working with HEMISPHERx again to commercialize this exciting technology," said Dr. Antonio Goncalves, Associate Vice Provost of Temple University. Oragen drugs are low molecular weight RNA compounds which the Company believes, by virtue of their small size and molecular stability, have the potential for becoming the first oral, broad-spectrum treatments for various viral diseases such as HIV infection and chronic HBV infection. Initial studies indicated that these drugs may withstand enzymatic destruction, an important factor in order for compounds to enter the blood stream in an intact form. Results from in vitro studies conducted in collaboration with the National Institute of Allergy and Infectious Diseases indicate that Oragen(TM) products may inhibit HBV infection, and in vitro studies conducted in collaboration with the National Cancer Institute and the University of Mainz, Germany, indicate that Oragen(TM) products may inhibit HIV infections. The Company believes Oragen(TM) drugs work at a different stage of the anti-viral and anti-cancer response chain than their current product in clinical testing, Ampligen(R), and therefore may be effective in disorders where the activity of Ampligen(R) is limited. The Company also believes that Oragen(TM) drugs can potentially be engineered to trigger specific responses in immune cells based on in vitro tests. CONTACT: HEMISPHERx BIOPHARMA, INC. R.
